C0875

Circuit Description
The yaw rate sensor reference voltage is monitored for an over or under voltage condition.

Conditions for Running the DTC
^ The ignition is ON.
^ The vehicle speed is greater than 40 km/h (25 mph).

Conditions for Setting the DTC
A malfunction is detected if the supply voltage is above 2.9 volts or below 2.1 volts for more than 200 milliseconds.

Action Taken When the DTC Sets
^ A malfunction DTC is set
^ TCS and VSES are disabled
^ TCS, PCS and SERVICE VEHICLE SOON lamp indicators are ON

Conditions for Clearing the DTC
^ The condition for the DTC is no longer present.
^ A history DTC will clear after 124 consecutive ignition cycles if the condition for the malfunction is no longer present.
^ Using a scan tool.
^ The EBCM automatically clears the history DTC when a current DTC is not detected in 124 consecutive drive cycles.

Diagnostic Aids
Possible causes of this DTC are the following conditions:
^ An open in the yaw rate sensor supply voltage circuit
^ A short to ground in the yaw rate sensor supply voltage circuit
^ A short to B+ in the yaw rate sensor supply voltage circuit

Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
2. Tests for specified voltage on the 5 volt reference signal circuit.
3. Checks to see if voltage was below specified voltage.
4. Checks to see if voltage was above specified voltage.
5. Tests for a short to ground in the 5 volt reference circuit of the yaw/lateral accelerometer sensor.
6. Tests for a short to voltage in the 5 volt reference circuit of the yaw/lateral accelerometer sensor.
7. Tests for a high resistance or an open in the ground circuit of the yaw/lateral accelerometer sensor.
8. Checks the yaw/lateral accelerometer sensor connector for poor connections.
9. Checks the EBCM connector for poor connections.
